Patents by Inventor Han B. Wang

Han B. Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Three-dimensinoal scaffolds, methods for fabricating the same, and methods of treating a peripheral nerve or spinal cord injury
    Patent number: 10413391
    Abstract: One aspect of the invention provides a three-dimensional scaffold including at least one layer of highly-aligned fibers. The at least one layer of highly-aligned fibers is curved in a direction substantially perpendicular to a general direction of the fibers. Another aspect of the invention provides a method for fabricating a three-dimensional scaffold. The method includes: electro spinning a plurality of fibers to produce at least one layer of highly-aligned fibers and forming the at least one layer of highly-aligned fibers into a three-dimensional scaffold without disturbing the alignment of the highly-aligned polymer fibers. A further aspect of the invention provides methods for using a three-dimensional scaffold to treat nerve or spinal cord injury.
